Simms’ Thermal OTC (Over The Calf) Socks stoke a fire under your feet thanks to premium merino wool.
The feet: first to get cold, last to warm up. We fish all winter: in the 30 degree rivers, or standing on two feet of ice. The socks we choose are important. These are our favorites for 2017/18. Big rich Merino wool-based socks with odor control.
